The DIPA 2000 micro particle size and shape analyzer is a unique instrument that contains 2 complementary and independent measurement techniques. The DIPA technology concept integrates laser and video measurement channels to provide complete sample information on particle size distribution and many particle shape parameters for the same sample. The sampled material has no direct contact with the DIPA 2000 instrument, allowing both laboratory and on-line analytical capabilities to handle extreme applications. It offers a wide variety of instruments and accessories for ultimate application solutions.

A focused laser beam rotates in a constant & steady frequency of 12000 rpm and randomly interacts with particles within the sample medium. Each randomly scanned particle obscurates the laser beam to a dedicated photo diode, which measures the time of obscuration. The time of obscuration directly relates to the particle's Diameter, by a simple calculation principle of multiplying the known beam rotation Velocity in the directly measured Time of obscuration, (D=V*t). This unique analytical technique is recently called "Laser Obscuration Time" (LOT) or former "Time Of Transition" (TOT). It demonstrates the major advantage of this direct particle size measurement over other laser used techniques, with high resolution obtained by the individual particle measurement approach. The benefit of measuring time (unlike other particles features) is its "sterile nature" as an analytical variable, meaning it is not affected by any physical or chemical property of the particle or its medium; in fact, it provides reliable analysis results for a wide variety of materials, where other common techniques can not overcome physical or chemical limitations. State-Of-The-Art software analyses the obscuration time as multiple pulses algorithm complex, providing within seconds clear and accurate results of the sampled particles size distribution. The DIPA 2000 real time sample visualization capabilities importantly allow its users to easily eliminate unwanted analytical results due to irrelevant and/or unwanted fractions in the sample: "Seeing Is Believing"!!!         The DIPA 2000 Video Channel performs Dynamic Size and Shape Analysis of the particles in dynamic flow (2 - 5,000 microns). This video channel is equipped with a CCD video microscope camera, synchronized strobe light illumination and the acquired images are displayed and analyzed by powerful image analysis software. The acquired images are automatically processed, analyzed and dozens of useful analytical parameters are automatically determined. Typically, thousands of imaged particles can be analyzed during a measurement cycle, providing reliable and robust statistics. User friendly software provides automated and advanced Image Analysis features that assist in optimizing sample measurement. Software algorithms enable automatic pre-programmed calculation for all of the available parameters including Ferret diameter, area, perimeter, circularity, aspect ratio, and many more useful size and shape analytical parameters. The software also offers powerful group filters that allow the measurement of specific particle groups within a complex mixture of different particles. All measurement results can be represented in multiple types of graphs and tables, and sample images can be stored for analysis at a later time. Our dynamic image analysis software can be also used as an analytical addition to a microscope station, providing the same useful size and shape information for particles captured by our CCD camera mounted on the optical microscope.
